That while he was with Messenger of Allah ﷺ who was accompanied by the people on their way back from Hunain, the bedouins started begging things of Messenger of Allah ﷺ so much so that they forced him to go under a Samura tree where his loose outer garment was snatched away. On that, Messenger of Allah ﷺ stood up and said to them, "Return my garment to me. If I had as many camels as these trees, I would have distributed them amongst you; and you will not find me a miser or a liar or a coward." (Using translation from Bukhārī 3148)
أَنَّهُ بَيْنَا هُوَ يَسِيرُ مَعَ رَسُولِ اللهِ ﷺ وَمَعَهُ النَّاسُ مُقْبِلًا مِنْ حُنَيْنٍ عَلِقَتْ رَسُولَ اللهِ ﷺ الْأَعْرَابُ يَسْأَلُونَهُ حَتَّى اضْطَرُّوهُ إِلَى سَمُرَةٍ فَخَطِفَتْ رِدَاءَهُ فَوَقَفَ رَسُولُاللهِ ﷺ ثُمَّ قَالَ أَعْطُونِي رِدَائِي فَلَوْ كَانَ عَدَدُ هَذِهِ الْعِضَاهِ نَعَمًا لَقَسَمْتُهُ ثُمَّ لَا تَجِدُونِي بَخِيلًا وَلَا كَذَّابًا وَلَا جَبَانًا
